How to Create a Bootable CHKDSK

By J.S. Copper

The Windows CHKDSK command detects and repairs errors or bad sectors of your computer's hard drive. You can run the process directly from Windows or with the Windows Setup disc. If you don't have the disc because Windows came preloaded on the computer, instead you can create a bootable system repair disk that allows you to access system recovery options, including the CHKDSK command.

Step 1

Right-click the **Windows** button on the desktop taskbar. Select **Control Panel** from the jump menu.

Step 2

Type **backup and restore** in the Control Panel search field. Select **Backup and Restore (Windows 7)** from the search results. This utility gives Windows 10 and Windows 8.1 computers access to the legacy system repair tool.

Step 3

Select **Create a system repair disk** from the menu on the left. Enter your Windows login credentials when prompted.

Step 4

Select the CD/DVD drive from the drop-down menu and click the **Create disc** button. Once complete, you will have a fully bootable disk capable of running the CHKDSK command.

Step 5

Insert the System Repair disk into the CD/DVD drive. Restart the computer to boot into the disk. Select your language in the on-screen prompt.

Step 6

Click **Command Prompt** from the System Recovery Options menu.

Step 7

Enter **chkdsk C:/r** and press the **Enter** key to scan and repair your hard drive from the disk.

Tips & Warnings

  • Your PC or laptop must have a CD/DVD optical drive for this process to work; you can't use a USB flash drive to create a system repair disk.
